An Approach to Fluctuation Modeling and Filter Design of Vehicle Oil Tank

The fluctuation model of vehicle oil tank is discussed and the description of the two-degree fuel dynamics characteristics in state space is presented in this paper. In order to simplify analysis and design, the approximate calculation of the oil fluctuation in the vertical direction based on pitch angle is addressed. Farther the road disturbances are divided into certain and random disturbance, resulting in efficiently analyzing the effects of different road conditions on oil fluctuation. Based on the typical road, the filter requirement and design method of oil data are given. Simulation and experiment results show that the fluctuation model and filter design method proposed in this paper are effective.
